Yield | Reaction Conditions | Operation in experiment |
---|---|---|
83% | With Oxone; ammonium bromide In methanol for 2 h; Reflux | General procedure: Oxone (1.352 g, 2.2 mmol) was added to the well stirred solution of substrate (2 mmol) and NH4Br (0.215 g, 2.2 mmol) in methanol (10 ml) and the reaction mixture was allowed to stir at room temperature (or reflux temperature). After completion of the reaction, as monitored by TLC, the reaction mixture was quenched with aqueous sodium thiosulfate, and extracted with ethyl acetate (3.x.25 ml). Finally, the combined organic layer was washed with water, dried over anhydrous sodium sulfate, filtered and removal of solvent in vacuo yielded a crude residue, which was further purified by column chromatography over silica gel (finer than 200 mesh) to afford pure products. All the products were identified on the basis of 1H NMR and mass spectral data. |
79% | With bromine In chloroform at 20℃; | Intermediate 119. 2-bromo-1-(3-fluorophenyl)ethanone; To a solution of 1-(3-fluorophenyl)ethanone (5 g, 36.2 mmol) in chloroform (34 mL) was added dropwise a solution of bromine (1.77 mL, 34.56 mmol) in chloroform (89 mL). The reaction mixture was stirred at room temperature overnight. The solvent was removed under reduced pressure and the residue was dissolved in methylene chloride (90 mL) and neutralized with sodium hydrogen carbonate (30 mL). The mixture was stirred for some minutes. The organic layer was extracted and washed with water, brine and dried (MgSO4). The solvent was removed under reduced pressure to give the title compound (5.99 g, 79 percent). |
62% | With N-Bromosuccinimide In ethyl acetate at 40℃; | 10mmol 3-fluoroacetophenone is added to a 100mL round bottom flaskAnd 11mmol of N-bromosuccinimide (NBS),35mL of ethyl acetate dissolved,Then add 1g of Amberlyst 15 ion exchange resin as catalyst.The reaction was warmed to 40°C and reacted. After TLC tracks the reaction,The reaction solution was filtered to remove Amberlyst 15 ion exchange resin, and the filtrate was spin-dried.Column chromatography (eluent: petroleum ether/dichloromethane) gave a pale yellow solid with a yield of 62percent. |
